Version 1.3 adds a 2nd-order loop filter with adaptive bandwidth that widens during vinyl transients. The original stardust.c v1.0 dropped sync whenever there was a scratch or surface pop on the record. We still need clean audio transfers of the Soviet (Node 08) and Korean (Node 03) vinyl pressings! -- Tyler MacDonald *PLONK* filter active for trolls.

Compiled cleanly under gcc -O2 on my Slackware box. The adaptive Costas loop is rock solid even on my scratched US copy. -- Lars Andersson | landersson@titech.ac.jp PGP Key fingerprint: F410 2073 D4E1 464E "Keep the channels open."
